Description

Support system for electrochromic devices
Technical Field
The present disclosure relates to electrochemical devices and support systems therefor.
Background
The electrochemical device may comprise an electrochromic stack, wherein the transparent conductive layer is used to provide electrical connection for operation of the stack. Electrochromic (EC) devices employ materials capable of reversibly changing their optical properties in response to an applied potential after electrochemical oxidation and reduction. Electrochromic devices change the color, transmittance, absorbance, and reflectance of energy by inducing a change in the electrochemical material. In particular, the optical modulation is the result of the simultaneous insertion and extraction of electrons and charge-compensating ions in the lattice of the electrochemical material.
Such devices may be located within a hollow glass unit that includes a space surrounding the electrochromic device. The surrounding space may protect and isolate the EC. The support system for such devices is required to maintain not only the integrity of the electrochromic device itself, but also the integrity of the surrounding isolated space.
Accordingly, further improvements in supporting electrochromic devices are sought.

"a" or "an" are used to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the invention. The description should be read to include one or at least one and the singular also includes the plural or vice versa unless it is clear that it is meant otherwise.
The use of the terms "about," "approximately," or "substantially" is intended to mean that the value of the parameter is close to the specified value or location. However, minor differences may prevent the values or positions from being exactly as described.
Patterned features including bus bars, holes, etc. may have a width, depth, or thickness, and a length, where the length is greater than the width and depth or thickness. As used in this specification, diameter refers to the width of a circle and minor diameter refers to the width of an ellipse.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The materials, methods, and examples are illustrative only and not intended to be limiting. To the extent not described herein, many details regarding specific materials and processing acts are conventional and can be found in textbooks and other sources within the glass, vapor deposition, and electrochromic arts.
Fig. 1A shows a plan view of a system 100 that may include more than one electrochromic device and a support system. Each electrochromic device may be located on a substrate and subsequently processed. In one embodiment, each electrochromic device may be processed as a laminate such that system 100 may comprise more than one laminate. In another embodiment, each electrochromic device may be processed as a hollow glass unit (IGU), such that system 100 may include more than one hollow glass unit (IGU), as described in more detail below with respect to fig. 3 and 5.
One embodiment of the system 100 may include a first electrochromic device 110 connected to a second electrochromic device 120 using a mount 130, as seen in fig. 1. In one embodiment, the mount 130 is a spider-like mount. In another embodiment, the mount 130 may be at the interface of the first electrochromic device 110 and the second electrochromic device 120. In one embodiment, the mount 130 is along the first side 115 of the first electrochromic device 110 and the first side 125 of the second electrochromic device 120, wherein the first side 115 of the first electrochromic device 110 is parallel to the first side 125 of the second electrochromic device 120. In one embodiment, the mount 130 may be positioned near approximately the center of the first side 115 of the first electrochromic device 110, as seen in fig. 1B. In another embodiment, the mount 130 (e.g., mount 130 b) may be positioned off-center from the first side 115 of the second electrochromic device 120. In another embodiment, the mount 130 is adjacent a corner of the first electrochromic device 110 and the second electrochromic device 120. In one embodiment, the mount 130 may connect two electrochromic devices. In another embodiment, the mount 130 may connect three electrochromic devices. In another embodiment, the mount 130 may connect four electrochromic devices. Thus, each electrochromic device may have 1 to 12 mounts. In one embodiment, each electrochromic device has at least one mount 130.
Fig. 2A, 2B, 2C, and 3 are schematic illustrations of a mount 130 for use in the system 100 of fig. 1, according to one embodiment. The mount 230 may include a body 231, arms 232, and pads 233. In one embodiment, the mounting member 230 is a continuous piece that is machined together. In another embodiment, the mounting member 230 may be comprised of several different pieces that are later attached together. The one or more mounts 230 in combination may be used to create a frameless support for one or more electrochromic devices. The mount 230 may be a spider hinge mount. In one embodiment, the arms 231 extend radially from the body 231. Each arm may include a varying thickness from the body 231 to the pad 233. In one embodiment, the arms 232 may lie in a different plane than the body 231. In one embodiment, the mount 230 has a height H that extends from the top surface of the body to the bottom surface of the pad 233. In one embodiment, the arms extend at a height of 80% to 95%. In one embodiment, the mount 230 may have 2 to 6 arms. In one embodiment, as seen in fig. 1B, mount 230 (e.g., mount 130 c) may have 2 arms. In another embodiment, the mount 130 may have 3 arms. In yet another embodiment, as seen in fig. 3, the mount 230 may have 4 arms.
A pad 233 may be attached at the distal end of each arm 232. In one embodiment, the pad 233 may be circular. In another embodiment, the pad 233 may be rectangular. The mat 233 may be any geometric shape, such as circular, square, rectangular, hexagonal, pentagonal, parallelogram, and the like. Each pad 233 may contact a single surface of electrochromic device 120. In one embodiment, each pad 233 may contact a single surface of the IGU. As seen in fig. 2B, pad 233a contacts first surface 211 of IGU 210 and pad 233B contacts second surface 221 of IGU 230, wherein first surface 211 and second surface 221 are parallel and lie on the same plane. Each pad may include an adhesive material that allows the mount 230 to support the first IGU 210 and the second IGU 220. The bonding material may be a non-penetrating bonding material. In one embodiment, the bonding material may be selected from the group consisting of transparent silicones, silicone elastomers, cured rubbers, VHB tapes, epoxies, and any combination thereof. In another embodiment, the pad 233 may be joined to the second pad 234 using nuts and bolts, as seen in fig. 2C. In one embodiment, the second pad 234 may be a similar material as the pad 233. In another embodiment, pad 234 may be a different material than pad 233. The second pad 234 may include an adhesive material to attach the mount 230 to the surface 211.
The pad 233 may contact a single surface without penetrating the IGU, thereby maintaining the hermetic seal and integrity of the electroactive device. Since the electrochemical device contains an electrochemical material that is sensitive not only to environmental factors but also to conductive elements, the active layer of the electrochemical device needs to be sealed from the environment. The active layer is protected from moisture and other contaminants by using a framing system that does not puncture or penetrate the active layer of the device or a sealed environment around the active layer. In one embodiment, the electrochromic active layer is sealed in a laminate. In another embodiment, the electrochromic active layer is encapsulated within an IGU, as depicted in fig. 5. Thus, any frame system that penetrates the active layer or double pane glass compromises the device integrity by introducing contaminants that may short the system or environmental factors (e.g., moisture) that may degrade the active layer. Advantageously, the support system of the present disclosure is non-penetrating, but still supportive, and is capable of withstanding a force load of 0.1MPa to 30 MPa.
